HOT-AIR REGISTER.

SPECIFICATION forming. part of LettersPatentNo. 790,625, dated. May 23, 1905. Application filed December 11, 1903. Serial No. 184,772.

To all whom it may concern.-

Be it known that I, CHARLES H. FOSTER, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented a certain new and useful Hot- Air Register, of which the following is such a full,clear, and exact description as will enable any one skilled in'the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to produce a register which will be very simple in construction, consisting of the fewest possible'parts, and at the same time will be neat in appearance, durable, and efficient.

Myv invention consists in part in the combination, with the fixed part of a register provided with a valve-opening, of a movable valve, of resilient material, for said opening, said fixed and movable'parts cooperating to maintain various relative resiliency of the valve.

My invention also consists in various other novel features and details of construction, all of which are described in the following specification and pointed out in theclaims affixed hereto.

In the accompanying drawings, which illustrate one form of register made in accordance with my invention, Figure 1 is a front elevation. Fig. 2 is an enlarged isometric projection of a part of the register. Fig. 3 is a section on the line 3 3 of Fig. l; and Fig. 4 is a view similar to Fig. 3, but showing the valve positions through the in its open position.

Like marks of reference refer to similar parts in the Several views of the drawings.

, valve-opening, in which is situated the grille or grating. The grille or grating consists of two integral sets of bars arranged at an angle to each other and in different planes, as described and claimed in my prior patent, No.

773,068, of October 25, 1904. This grille, however, in place of being made separate from the border or frame, as in my prior application, is formed integral therewith. The grille consists of a series of vertical bars 14 and a series of horizontal bars 15. The vertical bars 14 join the upperand lower sides of the frame or border and are slightly curved, as shown in Figs. 3 and 4. The horizontal bars terminate at the outside bars 14, so as not to make contact with the sides of the frame or border; By this construction I am enabled to cast the grille and border integral without injury to the border. If, however, the bars 15 were not curved or the bars 14 extended tothe sides of the frame, this could not be 'doue, because the'grille, containing less metal than the border, would cool 'first, and when the border cooled and contracted the pressure of the bars would disrupt the border. In my construction, however, the longbars15do not bear against the sides of the frame and the short bars, owing to their curved form, will give slightly to accommodate the shrinking of the-frame without exerting sufficient resistance to injure the frame. The central bar 14 terminates out of contact with'the upper side of the frame, and adjacent to it is formed a short bar 16. Between this short bar 16 and the central bar 14 is formed ashort bearingbar 17 for purposes hereinafter to be described. Thisbearing-bar 17 preferably has a rounded top, as shown in Figs. 3 and 4.

. 20 is the valve, which is formed of sheetsteel or other resilient material. The upper edge 21 'of the valve is reinforced, and the valve is carried in end supports 22 and sprung into 'a central notch 23 in the manner described and claimed in my prior patent above referred to. The upper portion of the valve 2O is-s'lightlycurved, and the curved portion preferably terminates in a' shoulder 24, and

said shoulder is preferably so formed as to fit square perforation 26, through which passes the body portion 27 of the member for retaining the valve in position.

Extending downwardly from this portion 27 is an arm 28, carrying a finger 29, whichv rests against the rear face of the valve, preferably directly above the shoulder 2 The upper and forward part of the body portion 27 is provided with a pair of wings 30, which rest against the front face of the valve. Extending upwardly from the front of the body portion 27 is a rounded portion 32, which bears against the cross-bar 17, hereinbefore described. Projecting from the rounded portion 32 is the operating-plate 33, by means of which the valve is opened and closed. The short arm 31 is also, preferably, provided with a detent 34:, adapted to bear against the top bar 15 when the valve is in its closed position, as shown in Fig. 3. The resiliency of the material of the valve will force the rounded portion 32 against the bearing-bar 17, so that the valve will be held by friction in whatever position it is placed. The required amount of friction can be obtained by properly proportioning the various parts of the register. The easiest way in which to regulate the pressure between the parts 17 and 32 is to vary the length of the finger 29, leaving the remaining parts of the register in the same proportion. It will be evident that by lengthening the finger 29 greater pressure will be obtained between the parts 17 and 32,

and by shortening the said finger less pressure will be obtained.

'In operation the valve of my register is opened by forcing the operating-plate 33 downwardly. This can be most easily accomplished by placing the foot upon the said plate. In order to close the valve, the plate is drawn upwardly, which would be most easily accomplished by placing the toe of the shoe underneath the said plate and drawing up upon it. The detent 34: serves to hold the valve firmly in closed position, so that it will not drop open when the register is being handled as, for instance, in packing or in placing the register in position in the wall of a building.

It will be seen that my register is very simple of construction and at the same time is reliable in operation and owing to the small number of parts and simplicity is not liable to get out of order.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

'1. In a hot-air register, the combination with the fixed part of a register having a valve-opening, of a movable valve of resilient material in said opening and provided with a bearing, and means dependent on the flexure of said valve in a transverse direction for forcing said bearing into frictional contact with the fixed part of the register.

2.
